install.php

Hi guys, I keep getting directed back to install.php. I have the exact scenario of how to trigger this to happen:

1. I am hosting a eCommerce site using WooCommerce plugin
2. I create a new product/blog post/post
3. For some reason, I will change the URL of the post for publishing purposes
– Example, I might draft a post and name it domain.com/12345
– When I am ready to publish, I will rename it to domain.com/how-to-post
4. After Changing the URL, when I click publish, my whole site will direct to the domain.com/install.php site and prompt me to install WordPress
5. After leaving it for 30mins – 1hour, my site will work fine again with the Changes saved.

Summary, everytime I edit the URL of any post, this issue will happen. This might be unavoidable because I have separate authors to upload posts. Author 1 will upload all the necessary information into the post and name it with a Code number. Owner will then instruct Author 2 to re-write post by providing the Code number. Author 2 will re-write, rename and change the URL. This is the process flow.

I understand this is probably some database issue because of changing Post URL, but I believe this should not happen.

Is there anyway I can prevent this from happening? Any advise please? Because we upload multiple posts daily and it will be a huge problem if we need to wait 1 hour for each post. Consuming too much resources.

Thank you.
